摘要
目前,学者对于UHPC的研究大多集中在其力学性能方面。本文以UHPC材料的性价比为研究目标,采用响应面-蒙特卡罗法构建响应面函数,并进行随机取样,研究钢纤维掺量对UHPC材料性价比的影响规律。分析了响应面-蒙特卡罗法参数的取值,发现随着钢纤维掺量的增加,UHPC材料的抗拉性价比和抗压性价比均减小。同时,得到了UHPC抗拉性价比和抗压性价比的最佳配比。
At present,most of the research on UHPC is focused on its mechanical properties.This paper took the costperformance ratio of UHPC material as the research objective,used the response surface-Monte Carlo method to construct the response surface function,and conducted random sampling to study the effect of steel fiber content on the costperformance ratio of UHPC material.The parameter values of response surface-Monte Carlo method were analyzed,and it was found that with the increase of steel fiber content,the tensile cost-performance ratio and compressive cost-performance ratio of UHPC materials decreased.At the same time,the optimal ratio of tensile cost performance and compressive costperformance ratio of UHPC was obtained.
